具有不同软硬结合位点（邻苯二酚和吡唑基吡啶）的双二齿桥联配体H2 L与Ti（IV）和Zn（II）的混合离子反应，得到由四个双核{TiZn（μ-L）2}单元通过甲氧基离子连接成环的八核杂金属Ti_4 Zn_4环状螺旋配合物。
A bis-bidentate bridging ligand H2L with inequivalent hard and soft binding sites (catecholate and pyrazolyl-pyridine, respectively) reacts with a mixture of Ti(IV) and Zn(II) ions to afford an octanuclear heterometallic Ti4Zn4 cyclic helicate formed from four dinuclear {TiZn(μ-L)2} units connected in a ring via methoxide ions.
